Editors for common.lvl files

[Fire]

Im not talking about how to edit common.lvl which is possible by Battlebelk's toolbox mod , but after you download that what are some good ways or downloadable things to edit the files after you download the toolbox , suggestions please

i dont think battlebelks toolbox is on here, if your talking about the thing rage has on his xfire thing, just screwing around with the core.lvl is fun to see the outcome of what you can change.
